TL;DR: Phishing-resistant device-bound passkeys are moving from specialist protection to baseline authentication, with Yubico arguing that broad deployment matters more than protecting privileged users alone. The deeper issue is that backup methods, recovery flows, and app-based MFA often preserve phishing exposure rather than removing it, so authentication governance has to change at the lifecycle level.
NHIMG editorial — based on content published by Yubico: Passkey myths and why phishing-resistant device-bound passkeys are the baseline
Questions worth separating out
Q: How should security teams implement passkeys without weakening phishing resistance?
A: Start with strict domain governance, enforce server-side verification of origin and rpIdHash, and keep challenge validation mandatory.
Q: Why do backup authentication methods often weaken passkey security?
A: Because the backup path is frequently easier to attack than the primary authenticator.
Q: What do teams get wrong about phishing-resistant MFA?
A: They often measure success by the presence of a strong factor instead of the absence of weaker bypasses.
Practitioner guidance
- Expand phishing-resistant coverage beyond admins Prioritise all employees, contractors, and high-risk business users for hardware-backed, device-bound passkeys rather than limiting strong authentication to IT and privileged accounts.
- Equalise recovery assurance Review backup methods, spare-device issuance, helpdesk resets, and alternate sign-in flows to ensure they match the assurance level of the primary authenticator.
- Map passkey lifecycle controls Document enrolment, reissue, repurposing, and retirement steps so the authenticating device remains governed across joiner, mover, and leaver events.

Phishing resistance is no longer a privileged-user requirement. The article correctly pushes back on the old assumption that only administrators need strong authenticators. Every employee can be phished, and less technical users often face the same initial access threat as privileged users. The practical conclusion is that assurance has to be universal if the organisation wants to shrink its login attack surface.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Secrets management fragmentation shows up in practice too: organisations maintain an average of 6 distinct secrets manager instances, according to The State of Secrets in AppSec.
A question worth separating out:
Q: Should organisations use the same authentication method for all users and use cases?
A: No, but they should use the same assurance standard where the risk is similar. Privileged access, sensitive applications, and remote access should share a phishing-resistant baseline, even if the form factor differs. Consistency matters more than one branded method, because fragmented exceptions create governance drift and a larger attack surface.
